As concerns changes from 4.4.4, there's nothing at all on the Solaris side, only the upstream changelog applies (a bunch of bug fixes).

Korona 4.4.5 is being uploaded to genunix.org - there are also no Solaris specific changes since Korona 4.4.3 (Korona skipped 4.4.4, as I was struggling with a bug in distro-constructor), apart from the KDE update also the following packages were bumped: amarok, boost, icu4c, konversation, libassuan, qimageblitz, qtcreator.

Several applications are starting and sometimes running slowly, most notably konqueror, this seems to be related to dbus - patches welcome.

Trent: I'm not sure what you're referring to.There's no change in Time slider at all.We do plan to integrate TS into Dolphin/Konqueror (https://defect.opensolaris.org/bz/show_bug.cgi?id=15428), but since the TS API has changed significantly around osol b140, we decided to wait for some post-b140 build to be published, rather than do the work twice
